[0048] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.

[0049] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0050] In related technologies, during the use of laser rangefinders, it is often necessary to replace the power supply module to meet the power requirements of the laser probe and related components. However, the operating environment of laser rangefinders is generally complex. When replacing the power supply module, external impurities can easily come into contact with the laser probe, affecting the measurement accuracy of the laser rangefinder. At the same time, during laser probe measurement, external impurities can also easily come into contact with the light-emitting surface of the laser probe, further affecting the measurement accuracy of the laser rangefinder.

[0051] Based on this, this disclosure provides a wireless laser rangefinder. The rangefinder includes an upper housing 1, a receiving housing 2, a lower housing 3, a laser probe 4, a partition plate 21, a protective component 5, and a power supply module 6. The upper housing 1 and lower housing 3 are detachably disposed on opposite sides of the receiving housing 2 in the height direction. The partition plate 21 is disposed within the receiving housing 2. The partition plate 21, the upper housing 1, and part of the receiving housing 2 form a first chamber 22. The partition plate 21, the lower housing 3, and another part of the receiving housing 2 form a second chamber 23. The laser probe 4 is disposed within the first chamber 22. The receiving housing 2 has a light-emitting hole 241 on the side near the light-emitting surface of the laser probe 4. The protective component 5 is disposed at the light-emitting hole 241 for protecting the laser probe 4. The power supply module 6 is disposed within the second chamber 23 and configured to supply power to the laser probe 4.

[0052] In this embodiment, the partition plate 21, the upper housing 1, and part of the housing 2 form a first chamber 22, in which the laser probe 4 is placed. The partition plate 21, the lower housing 3, and another part of the housing 2 form a second chamber 23, in which the power supply module 6 is placed. This separation of the laser probe 4 and the power supply module 6 prevents external impurities from contacting the laser probe 4 when the power supply module 6 is replaced, thus ensuring the measurement accuracy of the laser rangefinder. Simultaneously, the protective component 5 protects the laser probe 4, further improving the measurement accuracy of the laser rangefinder and extending its service life.

[0053] In some implementations, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The upper housing 1 can be detachably connected to one side of the receiving housing 2 via a snap-fit ​​connection. Specifically, the upper housing 1 has a deformable protrusion 12 on the side near the receiving housing 2. When the upper housing 1 and the receiving housing 2 are installed, the protrusion 12 can abut against the inner wall of the receiving housing 2, achieving an interference fit between the protrusion 12 and the side wall of the receiving housing 2, thereby realizing a detachable connection between the upper housing 1 and the receiving housing 2. As an example, the lower housing 3 can be detachably connected to the other side of the receiving housing 2 by bolt fixing.

[0054] It should be noted that the connection methods between the upper shell 1 and the receiving shell 2, and between the lower shell 3 and the receiving shell 2 described above are only examples. In other embodiments, the connection methods between the upper shell 1 and the receiving shell 2, and between the lower shell 3 and the receiving shell 2 are not limited to these.

[0055] In some implementations, see Figure 1 , Figure 6 The light-emitting aperture 241 includes a first aperture segment 2411 and a second aperture segment 2412 coaxially and interconnected. The first aperture segment 2411 is located close to the laser probe 4; the second aperture segment 2412 is located on the side of the first aperture segment 2411 away from the laser probe 4. The housing 2 has a first sidewall 24, and the orthographic projection of the first aperture segment 2411 onto the first sidewall 24 is located within the orthographic projection of the second aperture segment 2412 onto the first sidewall 24. It is understood that in this embodiment, the light-emitting aperture 241 is formed on the first sidewall 24; however, in other embodiments, to ensure the light-emitting efficiency of the laser probe 4, the opening size of the first aperture segment 2411 can be the same as the light-emitting surface of the laser probe 4, thus improving the protection effect of the laser probe 4 while ensuring its light-emitting efficiency.

[0056] In some embodiments, the protective component 5 includes a protective plate 51; the protective plate 51 is installed in the second hole section 2412 and is made of a transparent material.

[0057] As an example, see Figure 6 In this embodiment, the first hole segment 2411 is projected onto the first sidewall 24, within the projection of the second hole segment 2412 onto the first sidewall 24, and the first hole segment 2411 and the second hole segment 2412 are connected. Therefore, an installation step is formed at the intersection of the first hole segment 2411 and the second hole segment 2412, and the protective plate 51 is mounted on the installation step. Furthermore, in some embodiments, the protective plate 51 can be fixed to the installation step with adhesive, thus improving the fixing strength of the protective plate 51 while ensuring normal light output from the laser probe 4.

[0058] Furthermore, in some embodiments, the protective component 5 may also include a stabilizing plate 52; the first sidewall 24 and the light-emitting hole 241 are located on the same side and have a mounting groove 242, the orthographic projection of the light-emitting hole 241 on the first sidewall 24 is located within the orthographic projection of the mounting groove 242 on the first sidewall 24; the stabilizing plate 52 is disposed in the mounting groove 242 and has a stabilizing hole 521, the axial direction of the stabilizing hole 521 is the same as the axial direction of the first hole segment 2411, and the orthographic projection of the stabilizing hole 521 on the first sidewall 24 coincides with the orthographic projection of the first hole segment 2411 on the first sidewall 24.

[0059] It is understandable that the stabilizing plate 52 is provided with a stabilizing hole 521, which is the same size as the first hole segment 2411, so that the laser probe 4 can be properly operated while the protective plate 51 is further fixed in the second hole segment 2412.

[0060] In some implementations, see Figure 1 , Figure 4 The housing 2 has a second sidewall 25 disposed opposite to the first sidewall 24, and the length directions of the first sidewall 24 and the second sidewall 25 are the same; the housing 2 has a third sidewall 26 and a fourth sidewall 27; the length directions of the first sidewall 24 and the second sidewall 25 are the same; one side of the third sidewall 26 is connected to one side of the first sidewall 24, and the other side is connected to one side of the second sidewall 25; the length directions of the third sidewall 26 and the fourth sidewall 27 are the same, one side of the fourth sidewall 27 is connected to the other side of the first sidewall 24, and the other side of the fourth sidewall 27 is connected to the other side of the second sidewall 25; wherein, both the third sidewall 26 and the fourth sidewall 27 have a plurality of grip portions 28.

[0061] It is understood that the first sidewall 24 and the second sidewall 25 described in this disclosure have the same length direction because, in some embodiments, the first sidewall 24 and the second sidewall 25 are elongated. If, in other embodiments, the first sidewall 24 and the second sidewall 25 have other shapes, it should be understood that the plane containing the first sidewall 24 is parallel to the plane containing the second sidewall 25. Similarly, the third sidewall 26 and the fourth sidewall 27 have the same length direction, which can also be understood in this way, and will not be elaborated further here.

[0062] Further, see Figure 4 The hand grips 28 provided on the third side wall 26 and the fourth side wall 27 make it easy for operators to pick up the rangefinder in the measurement environment. At the same time, they can reduce the processing cost of the rangefinder and improve its aesthetics.

[0063] In some embodiments, the rangefinder further includes a power detection module 91; the housing 2 has a second sidewall 25 disposed opposite to the first sidewall 24, the power detection module 91 is disposed on the second sidewall 25, and the power detection module 91 is configured to detect the power level of the power supply module 6 and control the power supply module 6 to turn on or off. See details below. Figure 2 , Figure 3 , Figure 4 The power detection module 91 can detect the power of the power supply module 6. For example, the power detection module 91 has multiple indicator lights. When the power supply module 6 has sufficient power, the power detection module 91 makes the indicator light show the first state; when the power supply module 6 lacks power, the power detection module 91 makes the indicator light show the second state. The indicator lights can help operators to replenish or replace the power supply module 6 in a timely manner.

[0064] In some embodiments, the rangefinder further includes a charging module 9; the charging module 9 is configured to charge the power supply module 6 in response to an instruction from the power detection module 91. Specifically, when the power supply module 6 is low on power, the power detection module 91 can instruct the power supply module 6 to charge, thereby increasing the power supply module 6.

[0065] As an example, when the power supply module 6 has low power, the power detection module 91 issues an instruction to guide the operator to connect the charging module 9 to the power supply, thereby charging the power supply module 6. Alternatively, the charging module 9 can be directly connected to the power supply and used with the rangefinder.

[0066] As another example, the power supply module 6 may include a lithium battery module; the lithium battery module is detachably installed within the second chamber 23. It is understood that in other embodiments, the power supply module 6 is not limited to this, and this application will not elaborate further.

[0067] Further, see Figure 5 The lower housing 3 has a clamping part 31. The clamping part 31 can be used to press the power supply module 6 into the second chamber 23, preventing the power supply module 6 from becoming loose during use and improving the stability of the rangefinder.

[0068] As an example, the clamping part 31 can be a attachable foam. When the lower housing 3 is connected to the housing 2, the attachable foam can be pressed against the bottom of the power supply module 6, thereby fixing the power supply module 6 in the second chamber 23 to prevent the power supply module 6 from becoming loose during use.

[0069] In some implementations, see Figure 5The rangefinder also includes a first transmission module 7 and a second transmission module 8. The first transmission module 7 is located within the first chamber 22 and is configured to receive data measured by the laser probe 4 and transmit the data to the second transmission module 8. The second transmission module 8 is located within the first chamber 22 and is configured to transmit the data transmitted by the second transmission module 8 to an external receiving device. Specifically, after the laser probe 4 measures the distance between the objects to be measured, the laser probe 4 transmits the measured data to the first transmission module 7, which then transmits the data to the second transmission module 8. The second transmission module 8 then sends the data to an external receiving device for reference by the operator.

[0070] As an example, the first transmission module 7 can be a wireless data transmission board that can receive relevant data from the laser probe 4. It is understood that the wireless data transmission board is a technology well known to those in the art, and this application will not elaborate on it.

[0071] As another example, the second transmission module 8 can be a wireless antenna, which can receive and transmit data. Specifically, when the wireless data transmission board transmits the data measured by the laser probe 4 to the wireless antenna, the wireless antenna can transmit the data to an external receiving device for reference by the operator; when the operator adjusts the external receiving device, the external receiving device can send data to the wireless antenna, and the wireless antenna can send relevant instructions to the first transmission module 7 according to the instructions of the external receiving device, and the first transmission module 7 can guide the operation of the laser probe 4 according to the relevant instructions.

[0072] In some implementations, see Figure 1 , Figure 2 , Figure 5 The upper housing 1 has heat dissipation holes 11. The heat dissipation holes 11 can quickly dissipate the heat generated by the components inside the housing 2 during use, reducing the possibility of the rangefinder malfunctioning due to overheating.

[0073] In some embodiments, the lower housing 3 may be provided with at least threaded mounting holes (not specifically shown in the accompanying drawings of this application), and the multiple threaded mounting holes are located in the same axial direction, which facilitates the operator to install the rangefinder on the bracket for angle adjustment.

[0074] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.
